;********************************************************************************************************
;
;Very fast receive-routine for the 8xC592. It:
is embedded in the interrupt-handler for the CAN-controller,
uses the DMA-logic and
handles up to eight different messages
;(if these have the same leading 8 identifier-bits).
;
;To allow for faster receive-routine, it is assumed that all other routines
;accessing the CAN-controller, disable the interrupt of the CAN-controller
;(IEN0.5) during their execution.
